The slang term "tight" is generally used as an adjective to describe what something is like. A few synonyms of this word would be: awesome, cool, bodacious and impressive; some antonyms would be: stupid, dumb and idiotic. An example of the slang "tight" would be "Suzy's new video gaming system is tight" or "Bob just got this tight new hair cut."

I have no argument that "tight" essentially means "cool" or "awesome." However, we should not forget that those words are also slang.

"Awesome" literally means something that inspires the feeling of awe. "Cool" literally means to be slightly cold. The slang meanings of these words do not convey such strong emotions or literal sensations. These words basically boil down to saying something is acceptable, or that the speaker likes what is being described.

I point out that defining a slang term with other slang terms may engender more confusion; if someone does not know the definition of one common slang term, it is possible they will not know the meanings of other commonly used slang terms. Slang could be confusing to non-native speakers, so clarity is very important when explaining such terms.

Yes, "tight" in slang definitely can mean "cool" or "awesome." However, never use slang unless you're talking to someone you know or of like mind. Never use slang in formal writing, and never use slang when writing for businesses or online articles. The only reason to use slang is informal conversation. You can use slang in informal articles, but it must be clear when you do so.

For instance, if you're writing an article about blue jeans, you really have to watch out how you use the word "tight."

"These blue jeans are tight and definitely look good with a tank-top." -- Using "tight" this way makes it sound as if the pants fit really tightly to your body. Even if you said "These blue jeans look tight," then it still sounds as if they snug the legs.

So you see, you really have to use slang mostly in informal situations where you're actually talking to someone and not during your writing, unless it calls for it.
